Be it known that I, JOHN C. RAMSAY, a citizen of the United States, residing at Baltimore,.in the county of Baltimore City and State of Marylanchfliave invented certain new and useful Improvements in` Gas Burners; and I do declare the following to be a full, clear, and enact descrip-tion of the invention, such as will enable `others skilledv in the art to whichit appertains, to make and use the same. 4 y

This invention vrelates to improved gas burners such as are usedin connection with stoves, ranges, coffee urns, and the like.

TheV principal object. of the invention is to generally .improve upon burners of this type by the provision of one of extreme simplicity and durability wherein the body is solely composed of a common inexpensive pipe-section which is in one instance, an elbow, and in another, .a short threaded piece of pipe. f y

Another and very important obj ect of the invention is to provide 'a burner having a body of the typevabove mentioned, together with an inverted conical flame spreader disposed over the upper open end of( theibody anddetachably' connected to the latter.

Aj further and very important object of theinvention to provide a burner where` in the arrangement and construction 'of parts is suchthat the entrance of dirt, drippings, and grease, to the piping practically prevented. Thus. choking of the pipes is overcome and frequent cleaning is unnecessary. This important feattue should be carefully 'considered sincevit is not apparent in nor accomplished by the types of burners now patented andy marketed.

i Other objects and advantages of the improved burner will become vapparent from the following description and the features and novelty will lbe pointed out vin the appended claims. i i

In the accompanying drawings forming a part of this specification andv in which like numerals are use-d to designate like parts throughout the'same Y 'c i Figure l is an elevational view, with parts broken away and shown in section, of my improved burner, showing the same in use on a gas range.

designates the body ofthe burnerwhich solely 'composed Ifrom yay common ,elbow which is formed at tlieuncture of its hori-l zontal and vertical portionsjwith a screw-'v5 hole la. A pin 2 screw-threaded at itsfp-` posite ends, hasfits 'lower end screwed this hole and its upperyend extended. above the corresponding end of the '4. `elbon7 as shown. It is onto this -endthatv a' solid conical casting 3, constituting a Yllame, spreader, is screwed. rThis spreaderfisof a diameter considerably.greater thanthat of the elbow and ittherefore provide-s a relatively large flame of even distribution and intense 'heat whichI Will impin'ge theb'ottom ofthe cooking.utensils and effect arrentremely quick cookingv of the'. contents thereof.

'Associated with the horizontal" pertionw of the body -lis-a horizontal;conduit'i'e, which is preferably made lup `.of a long# screw 4a formed inyonev side with" an' air inlet opening 5 and provided at its?outer i end with internal screw-threads"intofwhich a screw-nipple 6 is tapped., The construe? tion of these part'swmayfbetter' Abe'see-itin Fig. 2.` Referring tothis'figure, fitfwill be seen that the nipple 6 is formed ati/its outer end with a 'restricted smooth ope'ni ing"7 wl1icl1 'is' lesigi1ed td'removablyvreceive lmie' end of theyvlalved passageA which connects ywith'the mainjor vsupply pipe B` of the range. Arranged on 'the screw-threads :of'jthe long-screw 42"" and Along'ritudinallly movable thereon, is a' valve 8 range or stove by means of av suitable two#` part bracket or clamp 11,"Which is'preferaroo bly removable.'A vThis clamp lmay vary in construction and'its exactconstruction need not therefore be" shown. However, it ls to be understoodthat-it isof such 'a construe with. .A nipple for attachment to to the purchaser.

the usual valved supply pipe A is threaded into the lower end of pipe 12, while a cross-pin 16y is secured therein near the upper end thereof. This pin 16 is provided with a centrally disposed screw hole, and the lower end of the vertical rod 17 is threaded into it, the spreader 3, which has been removed from the aforesaid rod 2, being screwed onto the upper end thereof.

In use, gas is fed through the pipes A and B and is permitted to enter the longscrew 4a, which constitutes a mixing chamber since it is equipped with air supply means as described. The quantity of air passing into this chamber may be restricted by properly manipulating the valve 8, which, in actual use, is equipped on itsouter face with nger-gripping lugs as shown to facilitate in rotating it. The combined mixture of air and gas passes on through the remainder. of this conduit and issues from theupper open end of the elbow where it is ignited to form the flame. As can be seen, the flame plays uponthe under face of 'the spreader plate and is diffused. over the entirev surface thereof and .passes .up and around the peripheral edge 17 and up against the bottomof the utensil on the supporting grid above 4this plate. Thus, a free fiow of gas is permitted and a hot uniform flame insured at all times.

From the foregoing description, it is obvious that I have devised an extremely advantageous and desirable burner which is, in the main, made up of a few simple and inexpensive couplings and pipe-fittings, all of which are so connected that they can be easily and readily separated for making repairs or'for cleaning. This is an important feature and should be carefully 'considered, especially in view .of the fact that the burner when soconstructed, can be manufacturedat an extremely low cost and can be retailed at a correspondingly Alow cost Then again, my flame spreader is such tlrat it cannot be easily displaced and sinceit is made in the form of a heavy casting, it is not very liable to be short-lived. Attention may also be directed to the fact that the spreader plate can be easily disconnected from the `vertical support-ing pin on the form of the invention shown in Figsl 1 and 2, and can be used on the remaining form of the invention Shown in Fig. 3. vMoreover, the burner is such that grease and dripping fluids cannot enter the piping to choke the latter. Hence, frequent cleaning, as is necessary with the common burner heads used, is entirely overcome. It may be added that although the burner is extremely simple in construction. and likewise inexpensive for both the manufacturer and user, it is quite as advantageous and effective in operation as the more expensive burners now used.

These and other advantages and features of the invention have, no doubt, become apparent from the foregoing description and drawings. Therefore, a: more lengthy and detailed description of the invention is deemed unnecessary.

I claim: l y

LA gas burner comprising a body formed from a common elbow having a screw-threaded hole formed therein at the juncture ofits horizontal and vertical porL tions; a relatively small vertically disposed pin arranged in the vertical portion of said elbow, being threaded at its lower end into said hole, and having its upper end screwthreaded and extending above the upper edge of the elbow; and a comparatively large solid inverted conical flame spreader threaded onto the upper end of said pin, said spreader being considerably larger in diameter than the yelbow and being spaced above the upper edge of the latter.

2. A burner for gas ranges comprising a horizontal conduit including a long-screw having `an air opening formed in one side and provided at its outer end with internal screw-threads, .a ring-nut on said long-screw serving to cover and uncover said air inlet opening, a screw-nipple tapped into said long-screw, having `a smooth restricted intake opening for removably receiving the usual valved pipe leading from the main fuel supply pipe on the range, an elbow conneoted to the inner end of said conduit, and a stationary flame spreader arranged over theupper open end of said elbow, being solely supported from the latter.

3. A. gas burner comprising a horizontal conduit including a long-screw having an air opening formed in one sidey and provided at its outer end with. internal screwthreads, a ring-nut on said long-screw serving to vcover and uncover said air inlet opening, a screw-nipple tapped into said longscrew, said nipple having a smooth restricted intake opening for-removably receiving the usual valved pipe leading from the main fuel supply/ pipe of the stove, a common elbow connected to the inner end ofsaid conduit, ysaid elbow having a screw threaded hole formed thereinv at the `juncture of its horizontal and vertical portions, a relatively small vertically -disposed pin arranged in the vertical portion of said e1- bow and having its lower end threaded into said hole, 'the upper end of said pin extending above the upper edge of the elbow, and a comparatively large inverted conical flame spreader threaded on to the upper end of said pin7 Said spreader being considerably larger in diameter than the elbow and being latter.
